How to backup IoP wallet and resync the blockchain

Hello, in this short video tutorial i will show you how to backup your wallet and how to resync the IoP Core Wallet So first i want to start with, how to backup the walletdat This is the file in which all your so called "private keys" are stored This is where all your IoPs are stored If you, lose this file, you lose all of your coins So before you delete anything of the IoP client or something similar Always, make sure to backup this file File is located in the IoP folder inside the %AppData% folder Here's how, to found it Here you see your wallet

dat file Please copy to a safe place Maybe twice or triple or whatever you want Maybe you use a thumbdrive or something similar But also, please keep in mind if someone else has this file from you it will, also have the full control over your IoPs But if you have set up a password it will also need a password to control your IoPs So maybe it's a wise idea to encrypt your wallet before that step And here i will show you how to do it And here you enter your password and save it Now, we come for the resync of the blockchain Nothing easier than this Just delete anything in the above folder EXCEPT the walletdat and start the Core Client again After full sync your IoPs are still there but the blockchain is completely new synced So, that's was it Have fun and stay safe!

How Blockchain Works CEO Talks with Coinsilium

The concept of technology Blockchain come a long way even in his short life but how it is adapted to support future business opportunities? Eddy Travia Director of Concilium joined us Concilium a listed company that helps the development of societies Emerging blockchain Eddy Welcome a fascinating subject and indeed it's early, but it's such a long way at such a speed that we need to talk about this in a little more detail, but first I want to understand what blockchain blockchain just Bitcoin is the underlying technology a decentralized registry which many transactions are recorded and linked to a chain of blocks essentially and Is directly related to the currency Bitcoin with Crypto or is it in general information? the feeling that he has solved the problem of double expense because many people try to digital cash but blockchain before you could not prove you're not spending the same twice the digital asset in a way then who owns blockchain I had to use blockchain for a process on which I look to make sure it works well? nobody really has the blockchain feel initially like blockchain Public blockchain is coded "open-source" So there are hundreds or thousands blockchain of which can coexist really in the world and you does not need a central authority or a centralized society to possess blockchain Where is this more applicable now? as I said it is expanding continuously this is a particular section works now? or it starts to be adopted more widely? obviously it started with transactional solutions type and Applications that means sending the value through the Internet in a way that could happen before but now because of its unforgeable recording data timestamp data blockchain it is used by many large institutions, including banks, insurance they experience for all see how it can improve their system and also be profitable in the future So there has been someone there in the process who wins the money or it makes the process easier cheaper more reliable faster? A bit of both! there are consultants are companies that sell solutions with blockchain but if you talk infrastructure systems you move on existing systems blockchain it is a long term process

People make money in this area which is really a type of model Business IT Infrastructure Company but it will take some time before these solutions are implemented Or do you see Coincilium in all this? How you stand? Early in 2013, we started the incubation companies, then we move to a more Traditional investment we call PVC which means that we are investing very early at the beginning and we want to help the construction of this infrastructure and build companies that will help large companies and other persons General to adopt this technology I'm curious to see where we are in the Will it be in 8 10, I asked this because a picked a quote here Deloitte says: "In 2025 almost 10% of all global GDP will stored on blockchain "Is this realistic? Do you think it's only 8 years old us? First of all this to change much over the last eight years in the world of Bitcoin and therefore blockchain for example in 2013, we could not imagine all applications and solutions that are work today especially with the advent of smart contracts makes this very interesting for people of businesses interact with the blockchain so I think in the future, there are many initiatives of governments want to move a large number of records, processes the blockchain so I think probably such studies seeking large-scale initiatives Could this be related the blockchain also? Any form of assets can be tokenized or be recorded on the blockchain You mentioned the word tokenized this is something we heard recently, tokenization national currencies

what it means and how it is linked to the whole idea of ​​blockchain? Imagine for example, instead of have our money we call paper money, it could be related a cryptocurrency eg 1 pound or 1 euro dollar we called Trustee cryptocurrency and there Many central banks and governments experiencing this and there are also private solutions and so I think we arrive at a convergence between technology and the government or institutions and major objectives implement this type of solution Do you see obstacles to Global adoption of this immediately? until now the main obstacle was regulations that most regulators were not very clear about their position regarding both the crypto-currencies because the technology is blockchain that technology and so can not really be regulated in that sense, but in terms cryptocurrency and regulations you need technical skills and there under construction solutions, but I would say that there are still efforts to be made to the general public the adopted wider The regulation is a very interesting concept car some organizations worldwide like to have control over things and crypto-currencies, their attraction I understand that they are outside and it is ca makes it attractive that you can sign border contracts You are not regulated! If you start to regulate this space cryptocurrency this he slows not the development and blockchain the idea of ​​such operations without constraints? It's a bit more complex in the direction eg

countries like Japan that accept Bitcoin pay for some services and they have adopted legislation this sense, they have integrated into their regulatory framework and the US Bitcoin or crypto-currencies are considered different types of jurisdiction or say different legal sense eg Treasury will see them as money and is considered a first material for CFTC or eg you must pay tax on capital gains So it is quite complex, in that but there are regulations as to Gibraltar example they build a regulatory framework for DLT and of course also this year after all these what we call the offer token token sales is another type of asset that is not an act but an application we call a Token App specific for Token and this can also lead to a different settlement You said DLT explain what that means

It's registers distribution technology or in other words blockchain in a much broader concept We addressed crypto-currencies Let's talk about this now about that there are many chatter around Crypto currencies but it always seems return to Bitcoin How do you Progress crypto-currencies over the next 10 years? you see the narrowing of options? You see disparaitre`? or do you see this wide range of cryptocurrency offers retain all their importance? Well, there are many new cryptocurrencies to come every day on Bitcoin market goal remains the hand reference and is the strongest network with a strong work capacity based on incredible computing power so I do not really change it is natural to say that Bitcoin is a reference in the crypto-currencies but hoes on there new crypto as Ether who also grew well because of their applications and new like ?? coming so I would say in the future Looks increasingly crypto currencies hit the market and of course some die and others will do better We have seen this year shift in power eg Bitcoin now represents only 50% of the total market capitalization of crypto-currencies and this has decreased this year because many many crypto-currencies came on the market

Or do you see Bitcoin within the next 12 months? I think it could easily reach $ 10,000 10,000 per Bitcoin in 12 months? Yes Driven by what? there are some technical steps on how new technology and what we call Forks without being too technical if they occur, say gently and also most Token sales happening on the network Ethereum, but in the future with solutions like SRK they could arrive on the Bitcoin network This will give a little say more weight in the landscape crypto-currencies fascinating topic Eddie thank you indeed to drop by to give us some of your time Eddie director Concilium a listed company that aid developing early stage TECH companies

How to Build an Ethereum Blockchain Explorer Dapp

– In this lesson, we're going to build a very simple dapp using the Ethereum blockchain as our backend We're going to build a blockchain explorer kind of like Etherscan, but we're only going to display the last 10 blocks on the chain

To do this, we'll use an opensource framework called ethersio to quickly develop and deploy our dapp Ethers comes with command line tools, which are available as a node module and can be installed using npm install ethers-cli Let's install to our global con-tax, since we'll probably use this across multiple projects You can read more about ethers by checking out their awesome documentation online

Ethersio makes it easy to create dapps by allowing you to quickly run them locally during development One of the things I really like is that it removes the need to have a copy of the blockchain, so we don't need to run a local geth node for example in order to build dapps Another thing I really like is that it comes with a free hosting service called ether space where we can store some of our static files for free We'll see how to use this later, but for now, we'll just keep everything local

The first step is to create a new project folder for our dapp and navigate into it We'll call our project explorer To use the ether's space hosting, we need to have an Ethereum account, and we can create one by calling ethers-build init, which generates a key file for us called accountjson Make sure you use a strong password when encrypting your private key

Your key files never leave your web browser's local storage when using ethers Now let's start by building our front end UI We can create a new html file called indexhtml and define a head and body for our document Let's put hello world in the body, and we'll also give our page a title

We can quickly spin up a local web server to serve this indexhtml by using the command ethers-build serve By default, ethers will point to the main net, but we can also pass the testnet option to point to robs-ton This prints out a local http address where we can see our UI Let's place this URL into a browser

We get some sort of view rendered, but this isn't like anything we wrote in our html We keep seeing this loading applications spinner because we haven't included the ethers app JavaScript in our document Let's add a script tag to the end of our body and link it to the minified ethers app JavaScript Now when we reload the page in the browser, we're at least able to see our hello world message, meaning our application is loading There's also a dashboard across the top of the page, but we didn't actually write any of this in our index

html This view is inserted by the ethersio container running locally Through the ethersio container, we can serve multiple apps by passing the application URL at the end of the fragment

The part after the hashtag tells the ethersio container which application to load Typically, we would have to run the ethersio container over https, but it allows for running over http for development The ethers

io container provides a bunch of other tools for us like a messenger, a testnet faucet, and even its own blockchain explorer But we won't get into these features right now Let's try to displaying the last 10 blocks from the blockchain in our UI We can replace our hello world text with an html table element that defines three column headers We'll print out each block's number, hash, and timestamp of creation

Let's give our table an ID so we can reference it later in JavaScript, and we'll also set the width to 100% We can define a new script element where we'll write some inline JavaScript Using the ethers variable, we can interact with the ethers API Let's start by setting a callback function for when ethers has loaded this application We'll print a simple message to the console

Running this in the browser with developer tools will demonstrate that it is indeed working Now let's populate our table with information once our ethers app is ready We can define an update blocks function, which will fetch the data for us Using the ethers variable again, we call the ethersblockchain

getBlockNumber method which will return a JavaScript promise, meaning the results will be returned asynchronously To handle the response, we use the then-function on the promise to pass a callback function Let's simply print out the block number to the console and verify that it's working in our browser We can verify the block number returned by cross-referencing it with the latest blocks listed on Etherscan We can see the last block number on the front page and verify that it's close to our value

The next step is to fetch the data for the last 10 blocks that came before this latest block number We'll do this using a simple four loop inside our callback function and then requesting the data for each block using ethersblockchaingetblock and passing in the block number This method also returns a promise, so we use then to provide a callback to it and handle the block data

For now, we'll just pass the block to a method called print block, which will display it for us The print block method gets a reference to the table using documentgetElementById and then adds a row to the end using tableinsertRow We insert three cells into this row for our data and then populate the cells using the block

Let's try this out in our browser If we refresh the page, we see a list of 10 blocks being printed out They're not in any particular order, since they're fetched and printed asynchronously Again, we can cross-reference the data on Etherscan to make sure it's correct And there we have our very first dapp

Within a few minutes, we were able to create a very basic blockchain explorer using ethersio We used only html and JavaScript to create our front end, and displayed data from the main net Ethereum blockchain Ethersio allows for creating your front end using any web technology, so you can still use your favorite front-end frameworks

In this example, the front end files were stored locally, and serve through a locally running instance of ethersio In the real world, we would need to host these static front end files somewhere The most convenient choice is to use Amazon S3, but centralized storage solutions aren't necessarily what we want We can also host our static files using decentralized storage services like IPFS or Swarm, which are essentially peer-to-peer data sharing networks kind of like BitTorrent

Is Bitcoin Just About Money? Find Out the Benefits of Blockchain and How They’ll Improve Our Lives!

VIDEO: Benefits of blockchain hi guys Nick here my friend Eric guys today we're going to talk about the utilization of blockchain in the news today there's a lot of talk about Bitcoin and other currency applications for blockchain but what a lot of people don't realize is there is some really really really big up-and-coming applications through the utilization of blockchain that people aren't really talking about or listening to so today we're going to cover some of those topics so listen up smart contracts are a huge utility of blockchain technology today and even more so into the future what smart contracts allow us to do is create a contract similar to a normal contract that you would sign today say for a law contract between two individuals we have a certain set of rules that are written out and you agree upon them with your signatures and this is done using black chain technology digitally so the advances of that are going to be one it's cheaper to transact than paying lawyers or say – it's also much more secure because it's decentralized software applications in blockchain technology are gonna be completely decentralized in Spain unencrypted in the blockchain itself this will go from video games Google to let's say service exchanges in Google for any kind of let's say a platform for social media any kind of digital and software development is going to be encrypted in the blockchain decentralizing file storage has obvious benefits by distributing data throughout the network it protects files from getting hacked or lost blockchain technology guys is gonna revolutionize the insurance market tricky aspect to pay attention first cheaper second less intermediate on third security each policy is going to be a smart contract encrypted inside the blockchain technology the use of crowdfunding in blockchain technology has raised over 1 billion dollars in 2017 alone outpacing venture capitalists this year look for crowdfunding and blockchain technology to be a big player in the future to come identification big utility here passport driver's license IDs this information will be encrypted in the layer of the blockchain and you will be able to access from ammo from your computer blockchain opens up the door for direct interaction between parties and it does this by having a peer-to-peer value of transfer thus opening up the door for a truly decentralized network creating a sharing economy are you guys so now that we've discussed the utilities of blockchain technology besides just its use as a currency we hope you understand the full range of utilities that blockchain can envelop and into the future we will only see more and more utilities come into fruition so if you guys are interested in some other topics that we didn't talk about please leave those down below we'll comment on it possibly Eric and I will make a video on it and also if you guys are interested in other things to do with blockchain technology and want to get a little bit more information click the link below and check out our website block capital insider or me and Eric oh and a much more in-depth about blockchain technology its uses and many many more things so thanks guys for coming out today we'll just really appreciate it Eric and I wouldn't be here without you guys we do I just want to say thank you so check back again for our next video

How Blockchain Technology Will Disrupt the World of Retail

Hey and welcome to Retail 90 I'm your host Tom We're hearing a lot about Blockchain at the moment but what even is it? And what could it mean for online retailers? First then the technical part, a blockchain simply records data in chronological order

The difference is the data is never stored centrally but it's distributed across multiple computer networks around the world And because the data base is distributed no one party can ever make any changes so it becomes permanent This makes it ideal for digital currencies such the famous Bitcoin but it's not all about banking the list of uses is growing and diversifying and the potential for retail is huge as well as protecting consumers from fraudulent transactions by creating a smart contract which holds back funds until everyone is satisfied – it can also be used to reduce other types of fraud and build consumer trust It creates a permanent record of a product's journey from supplier to customer so it can prove origin and authenticity whilst improving visibility on the supply chain What about warranties? Blockchain offers the possibility of recording all purchase transactions so no more shoeboxes full of receipts

And when it comes to customer loyalty how about the idea of using blockchain to record loyalty points for awards schemes Blockchain provides a better customer experience and for retailers it streamlines the exchange of information So where will this take us in the future? Well blockchain is likely to be a part of a product's whole life cycle even through to tracking new owners in the case of a resale And while it's hard to build trust in the wild wild west of today's internet Blockchain can fix that issue of trust which for online retailers can only be a good thing

But what do you think? Let us know your thoughts
